Hi everybody!

For better readability i start a new thread to continue the transformer tests  posted in the Lenz Force free power generation thread.

The goal is to get more information about the influence of windings, core materials and frequency on the fase shifting,

and the posibilities to delay the lenz effect in order to get a positive feedback of flux.

Here some results from a first test with the device used in the reduced reaction transformer test and a comparision with the same core and a standard secondary, the transformer is fed directly with a sinewave, without the resonant capacitor

this shot shows  inpur vs. output voltage with the  standard winding.

here with the RR.transformer winding

Input voltage and current in the RR. transformer.

and in the standard winding

 

 

the following shots shows input vs. output voltage with lower voltage level, you can see a different wave shape.

Vidura; It's Phase not fase.

Thank you for the correction, and sorry for my bad English.

Due to my lack of knowledge on this topic i have performed a test with a standard secondary winding, if somebody can explain me i will appreciate. The following three scope readings are 1. open circuit, 2. loaded 3. short circuited.the upper traces are input  U & I

below the secondary U & I

 

Unloaded you can see the expected 90° shift  for reactive power, loaded there is an increase in current  and a phase shifting towards the Voltage peak, until here all seems logical, but when shorted the secondary the current peak goes back to the 90° shifted position-reactive power, so a shorted output would not take power from the source??

In this test i have connected a common mode choke connected in opposed coils configuration en series with the primary coil,

here you can see an important increase of the impedance and thus rising of the input voltage.

(in order to get the same output i had to rise the input voltage)

Hello Vidura,

Interesting subject and it's nice to see people experimenting. I tryied this road some time ago, but not that succesfull. The problem was that whenever I managed to phase the secondary current and voltage, there was always a balance with the primary.

Anyway...The 3 scenario looks the most promising in your case. Try putting a low resistor accross the secondary and measure. I don't know the power in your setup but I recommend something low, like 5W or 10W resistor. While checking the phases of current and voltage you also have the posibility to touch the resistor and feel if it gets hot, so you'll have double check of validity that you truly have power going thru.

All the best.

Hey Vasile,

Zero Degrees is Real Power, so on the Secondary ( s ) this is what we want.

However, on the Primary, we want 90 or more degrees, the Power In then becomes the Power Out, thus we use no Power on the Input. All the Input Power, and more, is returned back to the Source for reuse.

Vidura is exactly on the right path - Well done Vidura!

He has shown that the Input Phase angles can be retarded by adding Load, which is reverse to normal Transformers - VERY Important concepts to understand correctly!

Good to see you back, its been a while!

Hi, If anyone have a explanation for the behaviour of the transformer when shorting the secondary there seems to be a phase angle of nearly 90° between primary current and voltage, these scope shots have been made with the standard secondary winding at 4khz. Does that actually mean that all power is returned to the source ,in the secondary is real power, as the shorted secondary becomes hot quickly? What about the fees of the electric companies for reactive power, it is said that they want to avoid harmonic distortion on the grid, or might it be that the meters don't work properly?

hello Vidura
All your answers are in this patent US9230730B2 Bitroidal transformer.

And I could also read on the following topic:
The charge seen by the primary when placing a load on the secondary of a transformer

follow established rules.
